EXHAUST NOZZLE Filed April 7, 1928 Patented dune 16, I 1931 BRADFORD L. MGLEOD, OF FRANKFURT, INDIANA EXHAUST NOZZLE Application filed April 7, 1928. Serial No. 268,318.

My invention consists in a new and useful improvement in exhaust nozzles for use on 10- comotives and is designed to provide an extremely simple and efficient nozzle having a 5; bridge dividing the throat into two passages. The particularly novel and useful feature of my device is the form and relation of the nozzle and bridge, the parts being so designed and proportioned as to render them is easy of manufacture and assembly, and extremely efiicient in operation as shown by practical experience in use.

In the drawings filed herewith, I have illus trated and have hereinafter fully described one specific embodiment of my invention, but it is to he distinctly understood that I do not consider my invention limited to said specific embodiment, but refer for its scope to the claim appended hereto.

In the drawings:

Fig. 1 is a plan View of my device.

Fig. 2 is a vertical section on line 22 of Fig. 1.

Fig. 3 is a vertical section on line 33 of 7 Fig. 1.

As disclosed in the drawings, my device consists of a nozzle N and bridge B therefor. The nozzle N has a circumferential flange 1 of any suitable configuration with bolt holes 3e 2 therein, by means of which the nozzle N can be suitably attached to the end of the exhaust pipe. i Vhile the outer face 3 of the nozzle N is substantially cylindrical, its inner face l is frusto-conical, converging toward the upper end of the nozzle N in a relatively constricted throat 5 having the rectilinear face 6. plane surfaced annulus 7. The bridge B consists of a bar 8 provided at each end with a plate 9 resting upon the annulus 7 and pro vided with a bore through which is received a bolt 10 suitably mounted on the annulus 7, the plate 9 being fastened to the bolt 10 by a nut 11. The bar 8 has adepending portion 12 with a rectilinear end wall 13 at each end,

received in the throat 5, the wall 13 abutting the face 6 of the throat5. The side walls 14 of'the depending portion 12 are convergent to form the knife edge 15, at the bottom of the bridge B.

inc top of the nozzle N is a Having described my invention, what I claim is:

In an exhaust nozzle the combination of a pipe having an upwardly-convergent inner face and a constricted cylindricaltln'oat with a rectilinear wall immediately above said face, and a plane-surfaced annular top immediately adjacent said throat; two bolts projecting from said top; a bridge having a wedge-shaped portion extendin into said pipe beyond said throat so as to e disposed in the convergent portion of said pipe, said wed e-shaped portion having rectilinear ends in juxtaposition with the wall of said throat; and a circular wing at each end of said bridge received upon the top and about one of said bolts.

. In testimony whereof I affix my signature.
